If you're playing 7.7, and particularly with a high level save from 7.6, the limit breaks come in trios every three levels or so and the jumps start to get pretty high after a point. On top of achievement bonuses crossing over, even a new game lets you get limit breaks pretty quick from how quickly you can level up. Plus unlike in 7.6 you only have a marginal amount of initial growth when putting your limit break in place. So achieving nigh infinite growth is significant more viable.
